产品亮点在回转工况调速控制、加长动臂式专用风机吊装臂架等方面实现技术突破,风机吊装就位精度达到毫米级,成功实现2.0~2.5MW山地风电低成本、高效率施工。该机为中联重科全新打造的800t级全新7节主臂91m长全地面起币机,专门针对风机吊装、大型石化塔罐吊装以及大型市政吊装需求开发。采用伸缩主臂+同定桁架段+毫米级微变幅段组合的风电专用动臂工况设计,整机运输成本低,风机工况仅需7台运输车即可完成转场。风棚工况装卸时间约为4h,效率高,操控微动性好,就位精度达毫米级。
Highlights Achieve technological breakthroughs in terms of speed control of slewing conditions and extension of lifting jibs for special boom booms. The precision of air blowers is about millimeter, and the successful construction of low-cost and high-efficiency 2.0-2.5MW mountain wind power. This machine is a brand-new 800t-grade 7-foot long arm 91m long all-ternary coin-operated crane of Zoomlion which is specially developed for fan hoisting, large petrochemical tower hoisting and large municipal hoisting demand. The use of telescopic boom with the same truss segment + mm micro-amplitude amplitude of the combination of special boom design boom conditions, the whole transport costs are low, fan conditions only 7 vehicles to complete the transition. Wind shed working conditions loading and unloading time is about 4h, high efficiency, good handling of micro-movement, in-position accuracy of millimeter.
